As shown in
The first bottom plate 1 and the second bottom plate 2 both have foldable structures. When an external force drives the folded side plate 3 to be folded, detachable interface sides of the first bottom plate 1 and the second bottom plate 2 are driven to be separated from each other and are folded adaptively, respectively.
A modular design is used for the box bottom plate. The box bottom plate is divided into a first bottom plate 1 and a second bottom plate 2, which are connected detachably, both have foldable structures and are movably connected with the folded side plate 3 and the fixed side plate 4, respectively, so as to achieve linkage folding between the side box plate and the box bottom plate. When the external force drives the folded side plate 3 to be folded, the folded side plate automatically triggers the separation and folding of the first bottom plate 1 and the second bottom plate 2, which does not need to manually adjust the position of the box bottom plate, simplifies the operation, improves the folding efficiency and convenience in use, and has strong practicability.
As an alternative embodiment, the first detachable interface side of the first bottom plate 1 and the second detachable interface side of the second bottom plate 2 are provided corresponding to a folding line of the folded side plate 3.
When the storage box needs to be folded, an external force is applied to the folded side plate 3. The folded side plate 3 starts to be folded along its folding line, and at the same time, the first bottom plate 1 and the second bottom plate 2 can be smoothly driven to move with respect to each other, so that the first detachable interface side and the second detachable interface side are separated from each other. When the folded side plate 3 is further folded, the first bottom plate 1 and the second bottom plate 2 are driven to be adaptively folded along their respective preset folding paths. The whole folding process does not need to manually adjust the position of the box bottom plate, which simplifies the operation and improves the folding efficiency and convenience of use.
As an alternative embodiment, the first bottom plate 1 consists of a first triangular folded plate 11, a first trapezoidal folded plate 12 and a second triangular folded plate 13, which are sequentially arranged along a length direction of the first detachable interface side and are connected by a hinging component.
The axis of the hinging component is the folding path, so that the first triangular folded plate 11 and the first trapezoidal folded plate 12, as well as the first trapezoidal folded plate 12 and the second triangular folded plate 13 can rotate with respect to each other to perform a folding action.
As an alternative embodiment, the second bottom plate 2 consists of a third triangular folded plate 21, a second trapezoidal folded plate 22 and a fourth triangular folded plate 23, which are sequentially arranged along a length direction of the second detachable interface side and are connected by a hinging component.
The axis of the hinging component is the folding path, so that the third triangular folded plate 21 and the second trapezoidal folded plate 22, as well as the second trapezoidal folded plate 22 and the fourth triangular folded plate 23 can rotate with respect to each other to perform a folding action.
As an alternative embodiment, the long side of the first trapezoidal folded plate 12 is connected with a fixed side plate 4 by a rotating component 8. The long side of the second trapezoidal folded plate 22 is movably connected with the other fixed side plate 4. The rotating sides of the first triangular folded plate 11, the second triangular folded plate 13, the third triangular folded plate 21 and the fourth triangular folded plate 23 are connected with the folded side plate 3 by the rotating component 8, respectively.
The first triangular folded plate 11, the second triangular folded plate 13, the third triangular folded plate 21 and the fourth triangular folded plate 23 rotate when the folded side plate 3 is folded. At the same time, because the first triangular folded plate 11, the second triangular folded plate 13 and the first trapezoidal folded plate 12 are connected by a hinging component, and the third triangular folded plate 21, the fourth triangular folded plate 23 and the second trapezoidal folded plate 22 are connected by a hinging component, the above components are hinged and matched with each other to rotate with respect to each other along the axis of the hinging component, so as to perform a continuous and stable folding action.
It should be noted that the rotating component 8 uses the prior art, as long as the relative rotation movement is achieved between the two connected components, and selection can be performed according to the use requirements, which will not be described in detail here.
As an alternative embodiment, the first detachable interface side is formed by a free side of the first triangular folded plate 11, a short side of the first trapezoidal folded plate 12 and a free side of the second triangular folded plate 13 together.
The second detachable interface side is formed by a free side of the third triangular folded plate 21, a short side of the second trapezoidal folded plate 22 and a free side of the fourth triangular folded plate 23 together.
Flange parts 5 and concave parts 6 are staggered and provided on the first detachable interface side, the second detachable interface side and the hinging sides of all folded plates.
Further, the flange part 5 and the concave part 6 are staggered and correspondingly provided on the free side and the hinging side of the first triangular folded plate 11, the short side and the hinging side of the first trapezoidal folded plate 12, the free side and the hinging side of the second triangular folded plate 13, the free side and the hinging side of the third triangular folded plate 21, the short side and the hinging side of the second trapezoidal folded plate 22 and the free side and the hinging side of the fourth triangular folded plate 23.
A concave-convex embedding connection method is used between the first detachable interface side and the second detachable interface side and between the hinging sides of two adjacent folded plates, which increases the contact area therebetween and improves the stability and reliability of connection under normal use.
As an alternative embodiment, the flange part 5 is provided with a buckle 51. The concave part 6 is provided with a clamping groove 61 adapted to the buckle 51.
Further, the buckle 51 is provided on the lower end surface of the flange part 5, and the concave part 6 is correspondingly provided with a clamping groove 61 adapted to the buckle 51. The buckle 51 is inserted downward into the clamping groove 61 to achieve the firm locking between the first detachable interface side and the second detachable interface side and between two adjacent folded plates.
When the folded side plate 3 is folded, the first bottom plate 1 and the second bottom plate 2 connected with the folded side plate are simultaneously driven to move with respect to each other, driving the buckle 51 to be disengaged from the clamping groove 61, and then separating the flange part 5 from the concave part 6. In this way, the first detachable interface side is unlocked from the second detachable interface side, and two adjacent folded plates are unlocked from each other. The first triangular folded plate 11, the first trapezoidal folded plate 12, the second triangular folded plate 13, the third triangular folded plate 21, the second trapezoidal folded plate 22 and the fourth triangular folded plate 23 adaptively rotate along their respective preset folding paths to perform a folding action.
As an alternative embodiment, the hinging component includes a sleeve 7 and a rotating shaft. The sleeve 7 is provided on the concave part 6 corresponding to the hinging side of each folded plate and is hinged with the rotating shaft.
Further, the sleeves 7 are provided on the concave parts 6 corresponding to the hinging sides of the first triangular folded plate 11, the first trapezoidal folded plate 12, the second triangular folded plate 13, the third triangular folded plate 21, the second trapezoidal folded plate 22 and the fourth triangular folded plate 23, respectively.
The rotating shaft passes through the sleeve 7 at the hinging side of the first triangular folded plate 11 and the sleeve 7 at the hinging side of the first trapezoidal folded plate 12 in sequence, so that the first triangular folded plate 11 and the first trapezoidal folded plate 12 can rotate with respect to each other along the axis of the rotating shaft as the rotating shaft, and the folding or unfolding action can be achieved. Similarly, the other two adjacent folded plates also rotate with respect to each other through the corresponding hinging component.
Referring to
In this way, since the elastic body 93 is provided, the folded side plate locking mechanism prevents people from sliding the lock body 91. As long as people press the lock body 91, the elastic body 93 is compressed to accumulate the elastic force. When released, the elastic body is restored to a non-pressed state under the action of the pressure accumulated by the elastic body 93, thereby achieving unlocking and locking between the lock body 91 and the lock tongue 92 and avoiding squeezing hands during sliding.
Further, the lock catch 911 is provided to be L-shaped. In order to facilitate the retaining ring to enter the U-shaped cavity encircled by the side surface of the lock body 91 and the lock catch 911, an inclined surface 916 is provided at an end of the lock catch 911 far away from the second folded side plate 32. When the folded device is opened, the retaining ring collides with the inclined surface 916 of the lock catch 911. The collision force on the inclined surface 916 can be decomposed into a force that compresses the spring. The lock body 91 is pushed to move toward the end where the elastic body 93 is provided, so that the spring can accumulate elastic force. The lock body 91 moves, which provides a space for the locking tongue 92 to enter the U-shaped cavity. After the locking tongue 92 enters the U-shaped cavity, the lock body 91 is restored to a non-pressed state under the action of the elastic force. In this way, when the first folded side plate 31 and the second folded side plate 32 are unfolded, the lock body 91 on the second folded side plate 32 can automatically lock the lock tongue 92 on the first folded side plate 31, thus avoiding people from locking manually, and saving time. At the same time, in the unlocking process, the lock body 91 is only pressed to achieve unlocking.
As an alternative embodiment, the lock catch 911 includes a second protrusion 9111 and a third protrusion 9112. The second protrusion 9111 is provided at a first side of the lock body 91, and the third protrusion 9112 is provided at an end of the second protrusion 9111 far away from the lock body 91. In this way, a U-shaped cavity is formed between the second protrusion 9111, the third protrusion 9112 and the side surface of the lock body 91, and the side wall of the retaining ring is provided in the U-shaped cavity. That is, the retaining ring is inserted in the space encircled by the second protrusion 9111 and the third protrusion 9112. When the lock body 91 and the lock tongue 92 are in an unlocked state, the retaining ring is capable of being separated from or entering the space encircled by the second protrusion 9111 and the third protrusion 9112. The first side is a side of the lock body 91 far away from the second folded side plate 32, that is, the inclined surface 916 is provided at an end of the third protrusion 9112 far away from the second protrusion 9111. When a collision occurs, the inclined surface 916 on the third protrusion 9112 is caused to be squeezed, and then moves along with the third protrusion 9112 toward the side where the elastic body 93 is provided, providing a space for the locking tongue 92 to enter the U-shaped cavity. At the same time, under the action of the elastic force, the lock body 91 is restored to a non-pressed state automatically.
As an alternative embodiment, in order to facilitate the installation of the elastic body 93, the second side of the lock body 91 is provided with a fourth protrusion 914. The second side is the side of the lock body 91 close to the second folded side plate 32, that is, the first side and the second side of the lock body 91 are two opposite sides. The lock catch 911 is provided at a side of the lock body 91 far away from the second folded side plate 32. The elastic body 93 is provided between the lock body 91 and the second folded side plate 32, and the elastic body 93 is provided between the fourth protrusion 914 and the second folded side plate 32, so that the lock body 91 can be switched between the locked state and the unlocked state. That is, when the elastic body 93 is compressed to accumulate the elastic force, the lock body 91 moves downward. The lock catch 911 on the lock body 91 provides an avoiding space for the lock tongue 92, which is convenient for the lock tongue 92 to enter the lock body 91. After the pressure on the lock body 91 is released, the elastic body 93 stretches under the action of the elastic force, so that the lock body 91 moves upward. In this way, the lock body 91 locks the lock tongue 92 to prevent the lock tongue 92 from being separated from the lock body 91.
As an alternative embodiment, in order to accommodate the elastic body 93 conveniently, the second side of the lock body 91 is provided with a first arc-shaped groove 913, that is, the side where the lock body 91 is provided with the fourth protrusion 914. Because the elastic body 93 is a spring and the spring is cylindrical, it is convenient to accommodate the spring and reduce the space for the spring to shake. In order to facilitate the elastic body 93 to be in contact with the second folded side plate 32, part of the elastic body 93 is provided in the first groove 913, and the other part of the elastic body 93 can be abutted against the installation position on the second folded side plate 32.
As an alternative embodiment, in order to ensure the firmness between the lock tongue 92 and the lock body 91, the second protrusion 9111 is provided in two places, that is, two places along the height direction of the lock body 91. The second protrusion 9111 at the first place passes through the through hole of the retaining ring, so that the side wall of the retaining ring is clamped in the space encircled by the second protrusion 9111 and the third protrusion 9112. The second protrusion 9111 at the second place falls directly below the retaining ring, so that the second protrusion 9111 directly clamps the side wall of the retaining ring on the outer side of the retaining ring.
As an alternative embodiment, in order to be pressed conveniently, the lock body 91 is provided with a pressing part 915, and the pressing part 915 is provided at one end of the lock body 91 far away from the elastic body 93.
Further, in order to install the elastic body 93 conveniently, the second folded side plate 32 is provided with a second groove 321. The elastic body 93 is installed in the second groove 321.
The above is only the specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions conceivable by those skilled in the art within the technical scope disclosed by the present disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
